This message came up when I did npm start
"start": "concurrently \"react-scripts start\" \"node server.js\"",
I am aware that this may not be an unusual activity. I just want a bit of clarification about the permission access.

@jsphkm Why did you close this? What did you discover?
I had some similar pop ups like these for other programs when macOS Mojave was released. I eventually dismissed it since the security was built into the os and was triggering these alerts for other apps that wanted access to stuff like files, e.g. vscode. However, I can reopen and continue this thread. Did you come across this problem too?
Yes, I suspect it has something to do with React wanting access to dev tools鈥攂ut I鈥檇 like to find out because even if it鈥檚 simply that, this permission is not a granular one and therefore it exposes a large attack vector for misbehaving/compromised/malicious code.
Had this popup when one of my instances was firing up a browser (strapi in this case).
